Abstract

The invention relates to a sealing agent, in particular to a sealing agent special for the rust prevention on the surface of an aluminum product. The rust-proof sealing agent is prepared by mixing the following components by weight percent: 62-70% of base oil; 20-25% of rust-proof additive; 1-2% of corrosion inhibitor; 1-2% of antioxygen, 1-2% of rust-proof film-forming agent, 3-5% of dewatering additive and 1-2% of coupling agent. The rust-proof sealing agent provided by the invention is used for the alkali resistance and the corrosion resistance on an aluminum product, can be nautically dried within tens of minutes, and is good in alkali-resistant and corrosion-resistant performance. Furthermore, the existing rust-proof sealing agent can not be dried until being heated in a drying way.

Description

technical field [0001] The invention relates to a sealing agent, in particular to a sealing agent specially used for antirust on the surface of aluminum products. Background technique [0002] At present, the research on aluminum anti-corrosion methods mainly includes oxidation anti-corrosion and organic coating anti-corrosion. Oxidation anti-corrosion can be divided into chemical oxidation, anodic oxidation, micro-arc oxidation, etc. At present, anodic oxidation and chemical oxidation are widely used in mature technology, and micro-arc oxidation will be the future development direction. The most widely used organic coating is UV curable coating. UV curable coating has high production efficiency and low cost. It is mainly used to decorate and beautify aluminum products, and also has a certain anti-corrosion effect. Although other thermosetting coatings, paints, etc. are simple in technology, they are complex in process, high in cost and low in production efficiency. [000...
